JULIUS G. SMITH, OF LUMBERVILLE, ASSIGNOR TO HIMSELF AND O. L. KNEELAND, OF FRANKLIN, NEW YORK.

MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 233,037, dated October 5, 1880. Application filed May 7, 1879.

To all whom it may concern:

Be it known that I, JULIUS G. SMITH, of Lumberville, in the county of Delaware and State of New York, have invented a new and Improved Milk-Cooler, of which the following is a specification.

The improvement will be first described in connection with the drawings forming part hereof, and then specifically pointed out in the claim. I

In the accompanying drawings, Figure l is a top plan or view of the improved can. Fig. 2 is a vertical section on line 00 .70 of Fig. 1. Fig. 3 is a plan of the stand or table, and Fig. 4: is a section of the same on line 1 y.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the cooler or outer shell of the can, having at the top a channel, a, formed by soldering a band around the inside of the shell to receive the flange of the cover B. This channel is designed to receive water or other suitable liquid for the purpose of sealin g the cover and preventing the entrance of air. In the apex of the cover is a hole for the reception of a tube, 1), which is held in place by a bail, c. The tube is provided with a collar, under which is a ring of packing, d. To the extended end of the tube a rubber tube is designed to be attached for the purpose of leading water down inside the can, for a purpose that will be presently referred to at length.

(J represents the milk-can proper. It consists of an annular chamber with a central space, D, through it, open at the top and bottom, while the diameter of the can is such as to leave a space, (1, between its outer walls and those of the cooler. From the bottom of the can projects a tube, 0, which is passed down through a hole, f, in the bottom of the cooler. Around the tube is a collar of packing, g, which, with the short leg h on the opposite sides, sustains the can above the bottom of the cooler, and thus leaves a space between the cooler and can at the bottom.

The canO is provided with a cover, E, with a hole in the center coincident with the space I), and with flanges to hold it on the can, as clearly shown in Fig. 2.

In the cover is a flanged opening, 2', just under a similar opening, i, in the cover B, both adapted to receive corks. These openings are designed to carry off the animal heat from the milk, and when the milk is cooled down the corks are to be inserted to prevent the entrance of air and dust.

Thespace d, between the can and the cooler, and the space under the can, are designed to hold water for cooling off the milk, while the space I) in the can is for the purpose of bolding ice or water, as may be desired. In case water is used, it is supplied through the tube 1) in the cover. From this tube it passes down into space D, and thence down through the space under the can into the surrounding space cl, thus surrounding the milk with wa ter, and also placing a body of water in its center in the space D, whereby it is cooled inwardly and outwardly.

The d rawin g-oft' tube 0, leading from the can, is fitted with a stopper, j, havinga corrugated conical extension, 70, and a wire handle, I, with a loop at the upper end in such a position as to enable it to be hooked over the edge of the can when the stopper is withdrawn, and hold the stopper out of the hole, but with the extension in the same. This opens the tube, and the corrugations give passageway for the milk, allowing it to pass off slowly, without eddies or whirls, thus preventingit from breaking up the cream and carrying it off with the milk.

In the bottom of the cooler is a waste-tube, l, witha stopper, m, provided with a hollowstern overflow, at, extending up nearly to the top of the cooler. In this tube, a short distance above the bottom, is a flanged opening, 12, adapted to receive a cork. This opening is designed to carry off the water slowly and pre- 7 vent it from rising too high in the cooler when ice is used. When the cooler is being washed the stopper is withdrawn entirely to allow the water to run off rapidly.

The stand F, for the can, has a bar, G, pivoted in the side plates, and on this is placed lengthwise a strip, 0, with two other strips, 19 p, at right angles thereto, forming the table.

To one end of strip 0 is fixed a lever, H, by which the table can be tilted back and. forth on the pivoted bar G. On the opposite side 100 of the stand is a pivoted stop, g, which, when thrown up straight, rests under one of the strips 1), while the arm of the lever, bearin g on the pin 1", holds the table level. On the end of strip 0 are segments 8 s, which clasp the sides of the cooler at the bottom and hold it securely on the table. The side of the table opposite that from which the lever is operated is connected by a cord with the spring 1, which assists in giving a rocking motion to the table and can.

The object in supporting the can on a pivoted table is to enable it to be rocked back and forth when it is being cleaned, so that the water can be agitated easily within it, and

thus greatly facilitate the work.

The waste-tube 1, leading from the bottom of the cooler, is to be furnished with a siphonnozzle, so as to water-seal the said tube and thus prevent the entrance of air.

The advantages of this invention will be apparent to those engaged in the dairy business. The trouble and inconvenience of sealing the cans by submerging them are entirely avoided. At the same time the air is effectually excluded and provision made for rapidly cooling the milk.

When the milk is all drawn off the creampan is placed under the draw-off tube 0 and the can agitated by rocking the table. The cream is then drawn off through the tube 0 without trouble. Then a small quantity of milk or water is put in and the can rocked. This will thoroughly rinse the can, and the cream will iiow out.

The cooler and can shown in the drawings are both round; but I do not wish to be confined to this form, as they can just as well be rectangular, oval, or of any other shape.

The can may also be sealed in a different way when water is used in place of ice. This is by making the cover E of the can with a broad flange extending far enough down the outside of the can 0 to project below the surface of the water in outside space, at, and central space, D. The flange must, of course, project lower down than the top of the overflow-tube m, so that the water will rise above the edge of the said flan ge before overflowin Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 111 a milk-can, the combination, with the outer cooler or shell provided with a rim-channel and a lid to fit therein in seal, of a waterdischarge tube projecting through said lid, and an inner milk-containing vessel or can of annular cylindrical form, raised above the bottom of the outer shell, and having a valved tube, 6, extending through said bottom, and a conforming lid, the parts being so related that water is discharged into the central well of the annular can and flows off at the raised outlet of the cooler or shell, as herein shown and described.

JULIUS G. SMITH.
